1 VPP, 11 µAPP
EnDat 2.1
EnDat 2.2
Supply voltage for encoders
DC 5.12 V ±0.15 V; max. 450 mA per channel
Overcurrent protection (automatic switch-off, resettable) at 550 mA
Input frequency

–
Subdivision factor
4096-fold
Signal adjustment
Automatic adjustment of offset, phase, and amplitude
Cable length1)
≤ 150 m
≤ 100 m
Data register for measured values
48 bits (of which only 44 bits are used)
Interval counter
Derived from Axis 1 (only 1 VPP)4),
Configurable interpolation factor from 1-fold to 100-fold
Can be used as a trigger source or additional counting axis
Measured-value memory
Typically 250 000 position values per channel
Measured-value trigger2)
Storage of the measured values of the four axes through an external or internal trigger (selectable).
External: • Signal via trigger input • Software command (over Ethernet)
Internal: • Timer and interval counter • Reference pulse of the respective axis (from Axis 1 and other axes)
Trigger input3)
9-pin D-sub connection (male); differential inputs as per RS-485 (terminating resistors can be activated)
Trigger output3)
9-pin D-sub connection (female); four differential outputs as per RS-485
Access to measured values
Depends on the selected operating mode (see separate table)
Software
Data interface5)
Ethernet as per IEEE 802.3 (10/100/1000 Mbit/s)
Network address
Automatic assignment through Dynamic Host Configuration Protocol (DHCP), or manual assignment
Dimensions
Approx. 213 mm x 152 mm x 42 mm
Operating temperature
0 °C to 45 °C (storage temperature: 0 °C to +70 °C)
Supply voltage
EIB 741: AC 100 V to 240 V (±10 %), 50 Hz to 60 Hz (±2 %); max. power consumption: 30 W
EIB 742: DC 24 V (–15 %/+20 %), max. 2 A
1) The supply voltage range of the encoder must be maintained; specified cable length applies when HEIDENHAIN cables are used.
2) Various trigger sources can be assigned to the individual axes.
3) Can also be used as logical input or output
4) Maximum input frequency during referencing: 70 kHz
5) The quality of the data cable between the EIB and PC must be adapted to the transmission rate and cable length.
